This invention relates to a chalk holder particularly adapted for use in connection with bowling alleys.

This application is a continuation in part of 5 application Serial No. 16,055, filed April 12, 1935,

now abandoned.

In accordance with the main feature of the present invention, a chalk holder is provided which firmly supports the chalk thereby preventing wastage thereof, and which is readily mounted on the top of a bowling alley post.

Other features of the invention will appear from the detailed description and claims when taken with the drawing, in which Fig. 1 is a side elevation of a bowling alley post with a portion of the ball supporting track attached thereto and with the chalk holder of the present invention mounted on the top thereof; Fig. 2 is a front elevation of the upper portion of the bowling alley post with the chalk holder mounted thereon; Fig. 3 is a vertical section taken substantially on the line 33 of Fig. 1; and Fig. 4 is a sectional view of the base of the chalk holder taken on the line 4-4 of Fig. 2, of the base broken away to show the means for adjusting the towel holder.

Referring to Fig. 1, 5 illustrates a bowling alley post of well-known construction to which there are attached the tracks 6 for supporting On the top of this post invention, which holder includes a circular metal base 8 having a downwardly extending flange 9 preferably of such diameter as to snugly fit the top of the post 5. Suitable screws Ill passing through holes in the flange, are screwed into the post to hold the base in fixed position thereon. The upper surface of the base has depressions 8 formed therein to retain cigars and cigarettes. This base which is preferably formed from sheet metal, has a centrally located neck portion H. A circular stamped metal cup 13 provided with a rim l4, externally threaded at I5, is formed with a downwardly projecting neck portion l2 adapted to be telescoped into the neck portion I l in which position the two portions are fastened together as by embossing.

The cup l3 has such a diameter that it serves as a socket to receive and support the base of a frusto-conical body of chalk H.

A pressed metal ring [8, U-

the cup.

It will be understood that when the ring is screwed on to the rim of the cup, the sloping flange 19 will grip the side surface of the body of chalk I? which will thereby have its base forced against the bottom of the cup so that the chalk is securely held in the holder. 5

The flange 9 of the base is provided with two pairs of oppositely disposed openings 2!, 22, adapted to receive a U-shaped towel holder made of metal rod stock and formed to provide two substantially parallel arms 23 connected by a lo cross piece 24. The arms 23 which pass thru the pairs of openings 2|, 22, in the space between the top of the post 5 and the holder base, are threaded at their free ends. Knurled cap nuts 25 engage the threaded ends of the arms 23 to 15 draw the cross piece 24 toward the flange 9 of the base so that a towel 26 inserted between these parts will be firmly gripped without danger of mutilation.

The preferred form of the invention has been disclosed but this disclosure is not to be considered in a limiting sense except as specifically defined in the following claims.

What I claim is:

1. A holder for retaining a frustro-conical body i of chalk comprising a base adapted to be mounted on a bowling alley post, a cup forming a part of said base and provided With an upwardly extending threaded annular rim to enclose the lower portion of said body of chalk, and a ring 30 having a downwardly extending inner and outer flange, said inner flange being adapted to engage a portion only of the side surface of said body of chalk, one of said flanges being threaded and being adapted to engage the threaded rim of said cup whereby the ring may be adjusted toward and away from said cup by a rotary movement.

2. A holder for retaining a frustro-conical body of chalk comprising a base adapted to be mounted on a bowling alley post, a cup forming a part of said base and provided with an upwardly extending externally threaded annular rim to en close the lower portion of said body of chalk, and a ring, substantially U-shaped in cross-section, having downwardly extending inner and outer flanges, said inner flange sloping outwardly to engage a portion of the side surface of said body of chalk, said outer flange being internally threaded and being adapted to engage the threaded rim of said cup whereby the ring may be adjusted toward and away from said cup by a rotary movement with the rim of the cup projecting into the space between the flanges of'said ring. v l

3. A chalk holder comprising a base member, adapted to be supported on a bowling alley post and being provided with a depending marginal flange for snugly engaging the side walls of the post at the top thereof, said base having a socket formed therein adapted to receive the bottom portion of a frustro-conical piece of chalk, a clampingmember detachably secured to the base and adapted to engage and to maintain the chalk securely in said socket.

4. In a holder, a base having two oppositely opening recesses therein, one recess adapted to snugly embrace the top of a bowling-alley post, the second recess being adapted to receive a frustro-conical preformed article therein, and a 7 gage the side thereof.
